The only acoustic panel that absorbs and diffuses in one piece — geometric oakwood face, studio-grade foam core. Decor-grade looks, NRC 0.64 performance, M1 fire-rated for commercial rooms.
The M1 fire-class foam behind the wood face captures mid- and high-frequency energy, cutting reverb and room muddiness on contact.
The 3D wood face breaks incoming sound into smaller, scattered reflections from 200 Hz to 5 kHz — so the room stays lively without becoming flat or dead.
Standard foam panels only absorb. Pure diffusers only scatter. Diffuse PRO does both at once — which is why it works in rooms where pure absorption would feel too "dead" (live recording rooms, listening rooms, restaurants, auditoriums).

Diffuse PRO is a combination absorber + diffuser. It reduces echo inside a room and breaks up flutter reflections. It does not block sound transmission through a wall.
| Metric | Value | What it means |
|---|---|---|
| NRC | 0.64 | Absorbs ~64% of mid/high-frequency sound energy on contact — high for a 2 in / 5 cm panel |
| Scattering range | 200 Hz – 5 kHz | Breaks up flutter echo across the full speech and music range |
| Fire class | M1 / Euroclass E | Meets commercial-install fire requirements in most EU and Asian markets |
| STC | Not rated | STC measures wall blocking. For noise transmission between rooms, use mass — not absorption. |
NRC 0.64 is the published overall figure for the foam-and-veneer assembly. Lab-measured.
Lay panels on the floor. Photograph the layout before mounting. Grid, staggered, or feature-wall — your call.
Construction adhesive for permanent installs. Heavy-duty Command strips or Z-clips for rental-friendly mounting.
Press firmly for 30 seconds. Start at the top of the layout and work down. Use a level for grid alignment.
For studios and listening rooms, prioritize panels at the first-reflection points on side walls and behind the listening position.
